Abstract

PROBLEM TO BE SOLVED: To facilitate the operation of style setting for typesetting of a structured document. SOLUTION: A conversion table generating part 104 analyzes a prototype SGML(standard generalized markup language) document, extracts document elements including a character string in element contents, urges a user to set style names corresponding to them and prepares a conversion table 122 showing the correspondence between the document elements and the style names. A style template preparing part 106 prepares a style template showing a list of style names included in the table 122. A document converting part 108 converts the tag of a prototype SGML document into a style tag by using the table 122 and prepares a typesetting format document. A typesetting editing part 20 receives the style template and the typesetting format document, displays a list of style names on the basis of the former and urges the user to set a style content corresponding to each style name. Because an item in which a style content should be set is automatically prepared, the user does not have to worry about which document element a style should be set to.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a typesetting device for typesetting a structured document.

[0002]

2. Description of the Related Art In recent years, various organizations including government offices have established SGML (Standard Generalized Mark-up Language).
Document management based on the concept of structured documents such as e) is performed. As is well known, SGML focuses on the hierarchical logical structure of a document, and structuring the document by adding a tag representing the logical structure of the element to each element constituting the content of the document. I have. By unifying the tagging rules, the consistency of the logical structure of similar documents is maintained, and the efficiency of document search and reuse is improved.

[0003] However, a structured document such as SGML exclusively defines the logical aspect of the document, and does not specify the visual aspect of the document, that is, the appearance / format in printing or image display. For this reason, when creating a publication by formatting a structured document, it is necessary to separately define the style of each part of the document. For the purpose of a structured document, there are usually many documents of the same structure, and it is common to set a common format for those documents and to perform automatic typesetting in accordance with the common format.

Conventionally, there are roughly two types of style setting methods for automatic typesetting of structured documents: a programming method and an interactive method. The former is a method of describing in a programming language how to format each document element of a structured document in a programming language, and the latter is a method of interactively setting a style for each document element using a GUI or the like. .

[0005]

The technique of style setting by programming requires a high level of knowledge and experience in both structured documents and programming languages. there were. There are systems that provide a script language that allows for easier style description. However, in this case, it is necessary to learn the script language, which also required some specialized knowledge. In particular, such a method based on programming or the like requires a large amount of time and effort since it is necessary to write a program for each type of application when processing various types of documents having different structures. Was.

An interactive setting method using a GUI or the like solves such a problem. However, a conventional system which provides an interactive style setting function is still insufficient in the following points. I couldn't say.

First, in some conventional systems of this kind, a page is displayed on an editing screen, and a user creates a typesetting layout by an operation of pasting each document element at a desired position on the page. The other type of document having the same structure can be automatically typeset using the typesetting information generated by this operation. However, this system had to deal with the structured context of the document in a programming manner. In other words, this system has realized a user-friendly operation environment at the level of how to arrange large document elements on a page.
In the end, the layout and style of the child elements and grandchild elements in the document element had to be described in a programming manner.

[0008] Some conventional systems of this kind provide a user interface for displaying a tree structure of document elements, selecting a document element on this display, and setting style contents. This system facilitates the setting of the style contents to some extent in that the position of the logical structure of the document element is easy to understand. However,
This system has a drawback that it is difficult to know which document element contains a character string to be styled.
That is, as is well known, many document elements of a structured document include only child elements in the element content and do not include a character string. In contrast, typesetting is a string,
Style settings are basically unnecessary for document elements that do not contain character strings. In addition, it specifies how the style content set for a certain document element affects the style of child elements, and if the user does not memorize it properly, the set style content has unintended side effects of the user In some cases.

Further, as a problem common to both the above-mentioned programming method and dialog setting method, it is extremely difficult to feed back a formatted result to a structured document. For example, in the programming method, a structured document is processed by a created program, so that the document is in a format that can be handled by an automatic typesetting apparatus. Generally, an automatic typesetting device has a function of editing a document in an internal format. For example, when a character error or the like is found by looking at a print result, the document is corrected using this editing function. I was able to. However, the conventional apparatus does not consider at all that the correction result is reflected on the original SGML, and it is necessary to use a separate SGML editor or the like to reflect the correction result. This point is the same in the case of the dialog setting method, in which the style information set in the dialog is applied to the structured document, converted to a document in a format that can be handled by the automatic formatting device, and the automatic formatting device converts the document to the document. Although corrections are often made, no tool has been provided that reflects the results of corrections made by the automatic typesetting device in the original structured document.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and facilitates the operation of style setting for automatic typesetting of a structured document, and can efficiently operate even when handling various types of structured documents. The purpose is to be able to typeset. It is another object of the present invention to provide an apparatus capable of mutually converting the format of a structured document including a style information that can be subjected to typesetting and a structured document.

[0011]

In order to achieve the above object, a typesetting apparatus according to the present invention analyzes a structured document, extracts a document element including a character string in the element content, and assigns the extracted document elements to each of the extracted document elements. A correspondence tag, assigning a style tag to each of the document elements, and generating correspondence information between each of the document elements and the style tag; and displaying a list of style tags in the correspondence information to correspond to each style tag. A style setting support unit for allowing a user to set style contents and generating a style template representing the set contents; detecting a character string of a document element from the input structured document; Conversion means for converting the structured document into a typesetting document by adding a style tag corresponding to the document element to the Interprets each style tags of formula document according to the style template, and wherein the typesetting string is added style tags in accordance with the interpretation result.

According to this apparatus, a document element including a character string which needs to be style-set for typesetting is extracted by the correspondence information generation unit, and a list of style tags corresponding to the document element including such a character string is obtained. The displayed style tag allows the user to set the necessary style contents for each style tag while viewing the style tag list. Therefore, according to the present invention, the user does not need to determine which element is to be styled as in the related art, and the style setting operation is greatly facilitated.

In a preferred aspect of the present invention, a means for including information of a document element of a higher hierarchy as the information on the document element extracted by the correspondence information generating means and the corresponding relation information; Inverse conversion means for converting the information into a structured document by referring to the correspondence information.

[0014] In this aspect, information indicating how a document element not including a character string is related to a document element including a character string is included in the correspondence information. Therefore, by using such correspondence information, the structure of all document elements of the structured document can be reproduced from the style tag of the formatted document, thereby converting the formatted document into a structured document. be able to. According to this aspect, when a correction is made to the formatted document obtained by converting the structured document, it is possible to obtain a structured document reflecting the correction result by inversely converting the corrected formatted document. it can. Further, a structured document can be obtained from a typesetting document newly created from scratch.

Further, in the aspect in which means for ensuring the uniqueness of each style tag in the correspondence information is provided, even if the arrangement order of the document elements is changed when the structured document is converted to the typesetting document, the typesetting is performed. The document element of the structured document can be correctly specified from the style tag of the formatted document, and the conversion from the formatted document to the structured document can be correctly performed.

In another preferred aspect, the attribute information described in the tag of the document element of the structured document is incorporated as a non-formatted comment sentence into the typesetting document, so that the attribute information is left in the typesetting document. Can be. Therefore,
Even if some modification is made to the formatted document obtained by converting the structured document and the result of the modification is inversely converted to the structured document, the attribute information is returned without loss.

In another preferred aspect, means for receiving designation of a character string to be automatically generated corresponding to a document element in typesetting output of a structured document; Means for assigning a style tag that can be distinguished from the style tag corresponding to the element, and means for setting the style content corresponding to the style tag of the automatically generated character string are further provided. As a result, a character string that was not present in the structured document can be reflected only in the typesetting result, and can be deleted when it is converted back to the original structured document.

[0018]

Embodiments of the present invention (hereinafter referred to as embodiments) will be described below with reference to the drawings.

FIG. 1 is a functional block diagram showing a functional configuration of a typesetting apparatus according to the present invention. As shown in the figure, the typesetting apparatus according to the present embodiment is roughly composed of a structured document front-end unit 10 and a typesetting editing unit 20.

The typesetting editing unit 20 is a device for typesetting a document in a specified format to generate a visible output such as a print output or a display output. In the present embodiment, the typesetting editing unit 20 has both an interactive typesetting editing function found in a DTP (desktop publishing) system and a batch processing (automatic typesetting) function.

In the typesetting editing unit 20, a document is managed in a form in which a tag (referred to as a style tag) representing designated contents (referred to as a style content) relating to a style is embedded.
For example, you can specify a typeface, font size, etc.
If you define a style, the typeface specified there,
The combination such as the character size is the style content. The style tag is basically used as a pair of a start tag indicating the start point of the style application range and an end tag indicating the end point. As a style tag, a name in which a style name (namely, a name indicating style content: called a style name) is surrounded by a predetermined symbol, for example, a pair of “<” and “>” can be used. In this case, the style tag with the style “Heading” has a start tag “<Heading>”,
The end tag is "</ headline>" or the like. The document in the typesetting editing unit 20 has a form in which start and end style tags indicating the contents of the style are added before and after the character string to which the style is applied. A document in such a format is called a typesetting document.

The above is a very schematic description of a typesetting document. In this embodiment, a more sophisticated tagging method is adopted. For example, a style tag is classified into several function types from the viewpoint of typesetting, and a tag indicating the function type added to a style name is used as a style tag. FIG. 2 shows an example of such a typesetting document. In the figure, a style tag 300 of “<P revision date>” is a combination of a symbol “P” representing a type of function on a typesetting “paragraph” and a style name “revision date”. The function type “P”, that is, “paragraph”, indicates that a style that can be defined in paragraph units is applicable. In the figure, the symbols “T”, “C”
Is used for the style tag, the former indicates a text function, and the latter indicates a comment function called “comment”. The type “text” indicates that a string-level style can be applied to the composition. The type “comment” is used to incorporate information that is not to be formatted into a document to be formatted. As shown in the figure, the end tag can be omitted from the style tag of the paragraph (P) or the comment (C).

The style can be freely set by the user as well as the style provided by the system. This setting is based on the style setting UI provided by the edit processing unit 210.
(User interface) 215. This UI
Reference numeral 215 provides a style name and style content setting screen, which can be used by the user to set the style name and style content. The style name created in this way and the information on the corresponding style content are stored in the storage unit 220 as a style template 222.

The editing processing unit 210 provides a UI for setting a style for a desired character string of a document for interactive typesetting editing. Using this UI, the user specifies a range of a desired character string and sets a style for the character string. This setting can be performed by displaying a list of registered style names and selecting the list by the user. The set style is incorporated into the typesetting document 224 in the storage unit 220 as a style tag.

The typesetting process in the typesetting editing unit 20 reads the style tag of the typesetting document created in this way, specifies the corresponding style content from the style template 222, and determines the characters within the applicable range of the styletag. It is an operation of applying to a column and converting it into data of a predetermined output format. The output format is, for example, a page description language such as PostScript (trademark of Adobe USA) widely used in the printing industry. The typesetting processing unit 230 performs the typesetting process in the typesetting editing unit 20.

As described above, the typesetting editing unit 20 has a function of interactively performing typesetting editing in response to an instruction from the user. In addition, the typesetting editing unit 20 reads a typesetting format document created by another device and automatically performs typesetting. It also has the function of performing

S stored in the document database 30
When a GML document is to be formatted by the typesetting editing unit 20,
It is necessary to convert the SGML document into a typesetting document that can be processed by the typesetting editing unit 20. This process is performed by the structured document front end unit 10. Further, the structured document front-end unit 10 also has a function of inversely converting a typesetting document created or corrected by the typesetting editing unit 20 into an SGML document.

In the structured document front end unit 10, the ESIS conversion unit 102 checks the syntax of the SGML document (instance), and checks the ESIS (Element Structure).
cture Information Set) format.

The conversion table creation unit 104 uses the ESI
Based on the data in the S format, a conversion table 122 for format conversion between the SGML document and the formalized format document is created. The conversion table 122 is basically a table indicating the correspondence between the document elements of the SGML document and the corresponding style tags, and is generated in the storage unit 120.
When creating the conversion table, the conversion table generation unit 104 assigns style tags to the document elements extracted from the SGML document. However, since the typesetting object is basically a character string included in the element content of the document element, the conversion table generation unit 104 identifies the document element including the character string in the element content and the document element not including the character string. Assign a style tag to the document element containing. In addition,
In some cases, it is desired to insert a character string that is not included in the original SGML document at the typesetting stage, but the present embodiment is designed to cope with such a case.

The style template creation unit 106 is a unit for creating a style template based on the conversion table 122. However, the style template created here is only a list of style names, and the style content corresponding to the style name has not been set. The setting of the style content is performed by the typesetting editing unit 20. In other words, if a style template with unset style contents is given to the typesetting editing unit 20, the style setting UI 215 of the typesetting editing unit 20 displays a list of style names in the template, and provides the user with the style contents for each style name. Prompt for settings.

The document conversion unit 108 has a conversion table 122
Is used to perform mutual format conversion between the SGML document and the typesetting document. This conversion process is generally performed in SGML
This is a process for converting tags between a document and a typesetting document. The conversion process of the document conversion unit 108 is performed by focusing on only the logical structure.
This is performed in consideration of the difference between the GML document and the typesetting result that emphasizes the typesetting style rather than the logical structure.

The processing control section 100 controls the processing of the entire structured document front end section 10 including the processing units described above.

The configuration of the typesetting apparatus according to the present embodiment has been described above. As described above, this typesetting apparatus provides an automatic typesetting function, a function of creating an SGML document from a typesetting document, and a user interface function that can easily create conversion information such as a conversion table used for these processes. provide. Hereinafter, the procedure of the typesetting process in the apparatus of the present embodiment will be described.

[Preparation Stage] A procedure for creating a conversion table and a style template used for automatic typesetting and the like will be described.

(1) Creation of a Model SGML Document A user creates a DTD (document type definition) of an SGML document to be automatically formatted, and creates a model SGML according to the DTD.
Create a document. Since the template SGML document is only used as a template when creating a conversion table and a style template, the content of the document (the content of the character string) may be anything. In other words, it is only necessary that tags are attached in accordance with the DTD. In particular, for the purpose of typesetting, any character string may be described in a document element including a character string.

For example, an SG having a hierarchical structure as shown in FIG.
Consider an ML document. In this document, each box 400 indicates a document element, and the character string inside the box indicates the element name of the document element. The line connecting the boxes represents the parent-child relationship between the document elements, and the box on the left of the line is the parent of the box on the right. For example, this document "Attachment"
Is a description of the medicine, which is composed of two document elements, "bibliographic matter" and "body". Also, for example, a mark 410 including an asterisk (*) is subordinate to the document element “revision date”, which indicates that “revision date” includes a character string as element content. Similarly,
“Version number”, “main document”, etc. having the mark 410 as a child also include a character string in the element content. On the other hand, a document element having no child 410 such as “attached document” or “bibliographic matter” does not include a character string in the element content. FIG. 4 shows an example of a template SGML document having the document structure shown in FIG. As in the SGML document shown in FIG. 4, the user adds a tag correctly and describes an appropriate character string where a character string should be, thereby creating a model SGML document.

The creation of such a model SGML document is as follows.
This may be performed using an SGML editor or the like.

(2) Creation of Conversion Table Next, the template SGML document is read by the structured document front-end unit 10, and the conversion table 12 for automatic typesetting is read.
Create 2.

In the creation of the conversion table, first, the ESIS conversion unit 102 applies an ESIS conversion to the read template SGML document.
SIS conversion processing is performed. Next, the conversion table generation unit 104 converts the SGML document based on the ESIS conversion result
Document elements having a character string in the element contents are picked up, and these are written in the conversion table. At this time, each document element is entered in the conversion table in a form that can be uniquely specified in the document structure using the ESIS conversion result.

FIG. 5 shows an example of the conversion table. This conversion table enumerates the document element type 500 and the corresponding style name 510. The document element type 500 has a tree structure in order from the root for each document element whose element content includes a character string. The names of the document elements up to the document element are listed. For example,
In the examples of FIGS. 3 and 4, the first document element “revision date” including a character string is “bibliographic matter”, “revision history”, and “revision date” in order from the root element “attachment”. Are listed in hierarchical order. By the permutation of the element names, a document element “revision date” having a character string in the element content is uniquely specified. Other document elements having a character string ("version number", "main document", etc.) are entered in the same manner.

The process of registering information of a document element having a character string (document element type 500) in the conversion table is automatically performed by the conversion table generation unit 104. On the other hand, the style name corresponding to the registered document element is set by the user. That is, the conversion table generation unit 104 completes the registration of the document element type 500 in the conversion table,
A conversion table in which the style name 510 is not entered is displayed on the screen, and the user is prompted to enter a style name corresponding to each document element. The user fills in the style name accordingly. The style name is S from the formatted document described later.
For conversion to a GML document, it must be unique within one document structure (ie, one conversion table). For this reason, the conversion table generation unit 104 manages so that the same style name cannot be set in one conversion table, and displays a warning message to that effect when the same style name is input by the user. To prompt the user to change the style name. In this way, a unique style name in the typesetting document is set for each document element and registered in the conversion table.

The setting of the style name is not limited to the method in which the user enters from the blank state as described above. As a modified example, for example, SGML is
It is also possible to automatically generate a style name based on the document element name of, and to allow the user to make changes to his / her preference. Also in this case, the uniqueness of the style name is ensured by the conversion table generation unit 104.

Further, the conversion table generation unit 104
If you want to insert a character string that is not included in the GML document
It is possible to receive a special processing specification such as when it is desired to format a part or all of the contents of the ML document in a tabular form, or when formatting a certain document element in a position different from the order in the original SGML document. Such a special designation is set in the column of the special designation 520 in the conversion table. For example, the user specifies special specification 52 of a document element for which special processing is desired.
When the column of 0 is selected with a mouse or the like, a setting screen for some prepared special processing is called up, and the user inputs desired processing types and processing parameters.

Each of the special processes will be briefly described. First, when it is desired to automatically generate and format a character string that is not in the original SGML document, for example, the document element “<Main Document>” in the example of the SGML document in FIGS. 3 and 4 includes a character string of the document name in the element content. However, there is a case where a heading such as “[main document]” is inserted before the document name. In such a case, the user:
Another table that stores the specially designated contents for each document element may be created, and the designated contents may be registered in this table. Alternatively, a document element into which a character string is to be inserted may be selected on the conversion table (FIG. 5), and the character string to be inserted may be input. Character string insertion can also be specified for elements that do not have a character string in the element content, such as <Usage Notes>. Such specification information is registered in the special specification column 520.

When performing tabular formatting, for each document element to be tabulated in the conversion table, it is specified which row or column of the table the document element is to be assigned to. This designation information is registered in the column of special designation 520.

When the user wants to move the document element to a position different from the position in the SGML document and format the document element, the user selects the document element with a mouse or the like and further designates the destination. The destination is specified by a method such as specifying the immediately preceding document element. For example, if you want to typeset the content string of the document element <main document> after the element <symptom> string,
Specify <symptom> as the destination. This destination information is also registered in the special designation 520 column.

When the designation of the style name and the special processing is completed, the conversion table is completed. The completed conversion table is stored in a form in which the correspondence with the original SGML document can be understood. For example, the identification name or file name of the DTD may be added to the conversion table as additional information.

(3) Creation of Style Template When the conversion table is completed, the style template creation unit 106 creates a style template listing style names appearing in the typesetting document by referring to the conversion table. FIG. 6 shows an example of the resulting style template. In the style template, a style name and a corresponding style content setting column are paired.

In the style template, both a style name corresponding to a document element having a character string and a style name of a character string automatically generated corresponding to the document element as special processing are registered. The latter style name is automatically generated by adding a reserved word indicating an automatically generated character string such as "auto" to the name of the corresponding document element. For example, the style name of the character string "[main document]" automatically generated in correspondence with the document element <main document> is automatically generated as "auto main document" by the style template creating unit 106. In the example of FIG. 6, the automatically generated character strings are registered for the four elements of <Note on use>, <Important note>, <Interaction>, and <Main document>. The automatically generated character string is generated at the position of the corresponding document element, and if the document element has a character string in the element content, it is output to the one before or after the character string, whichever is specified by the user in advance. Is done. Therefore, the style name of the automatically generated character string is arranged before or after the style name of the corresponding document element, whichever is set.

The style name of the document element for which the typesetting output position is specified to be moved as a special process is registered at the destination position on the style template. For example, FIG.
As shown in the figure, the element <main document> is 3 in the SGML document.
Is the string-owning element, but the element <
If it is designated to move after the symptom>, the style name "main document" is registered after the "symptom" as shown in FIG.

Although not included in the example of FIG. 6, when the output in the table format is specified, the style name of the entire table is preceded by the style name of each of the document elements constituting the table. Is generated. In this style name, style contents relating to the entire table, such as the style of the table ruled line, are set.

In the style template created in this way, the style content column is blank at this stage. The style template created in this manner is added with information that indicates the correspondence between the original SGML document DTD or the conversion table. The style content is set by the typesetting editing unit 20 thereafter.

(4) Data transfer to the typesetting editing unit When the conversion table and the style template with unregistered style contents are created in this way, the template SGML document is converted into the typesetting document using the conversion table. Then, the conversion result is passed to the typesetting editing unit 20 together with the style template. The conversion of the template SGML document is performed by the document conversion unit 108. That is, the document conversion unit 108
Reads the template SGML document from the beginning, finds the character string of the element content, specifies the style name corresponding to it from the conversion table, and adds the tag (style tag) of the style name to the character string I will do it. Also,
The document conversion unit 108 refers to the information of the special specification 520 of the conversion table and inserts the character string and the style tag into the document if the automatically generated character string is specified.

If the movement of the output position of the document element is designated in the special designation 520, the character string and the style tag of the element content of the document element are moved to the designated movement destination, and at the same time. A description is added to the original position to indicate that the character string has been moved to the original position. This is a process for enabling the reverse conversion of the typesetting document into the SGML document. In the typeset document of Figure 2 illustrated above,
The third line is a description indicating the original position. This example shows a case where the character string of the element <main document> located third in the order of appearance in the original SGML document has been moved to the end of the document. A description “movement destination symptom” indicating that the destination of the character string is after the element <symptom> is incorporated in “<C...>”. In the typesetting document according to the present embodiment, the comment must be attached to the character string, so that the comment description is added to the dummy character string. The dummy character string is predetermined so as to be ignored during typesetting. Since it is necessary to add a style tag to this dummy character string in terms of format, a tag “<T auto>” is automatically generated and added. The character string “auto” in the style tag represents an automatically generated character string. The character string to which the style tag including the “auto” is added is ignored when reversely converted to an SGML document. Is not incorporated into the SGML document.
Also, in the case of the character string of <main document> moved to the end of the document, the information of “return destination” indicating which position to return to when converting to SGML is the case of the aforementioned destination. As with, it is inserted in comment format.

Although not included in the example of FIG. 3, when the output in the table format is specified, style tags indicating the start and end of the table are set at the start position and the end position of the table content in the typesetting document. In addition, a tag for separating lines is inserted to indicate how far of the character string in the table contents constitutes one line of the table. This enables tabular typesetting.

Although not included in the example of FIG.
An attribute set for the element may be described in a tag of the ML document. In the present embodiment, since the reverse conversion from the formatted document to the SGML document is also considered, the information of those attributes is not lost when the SGML document is converted into the formatted document. In particular,
A measure is taken to add attributes in comment format. To explain with an example, for example,

If there is an SGML document element of <XX ZZZ = ddd> yyyy </ XX> (in this case, ZZZ =
ddd is attribute information), and in a typesetting document, conversion is performed as follows.

[0057]

## EQU2 ## For example, if the SGML document shown in FIG. 4 is converted, a typesetting document as shown in FIG. 2 is obtained. <P XX><Tattribute> Team <C attribute ZZZ = ddd></T> yyyy

As described above, when the template SGML document is converted into the typesetting format, it is transferred to the typesetting editing unit 20 together with the style template. This delivery is LAN
Or a portable medium such as a floppy disk. Further, the structured document front end unit 10 and the typesetting editing unit 2
If 0 is an application that runs on the same operating system, it may be passed through the operating system.

(5) Style Content Setting The typesetting editing unit 20 that has received the conversion result of the template SGML document and the style template stores them in the storage unit 220.
To memorize. Then, an editing screen 600 as shown in FIG. 7 is generated by the editing processing unit 210, and the style contents are set using this. In this editing screen 600,
A document content display portion 610 for displaying a document content portion and a style name list 620 for displaying a list of style names are provided. In the document content display section 610, character strings of the document content included in the typesetting document are displayed in order. Each character string in the display unit 610 and each style name in the style name list 620 are linked to each other, and when one is selected with the mouse, the other is simultaneously selected (for example, in a display mode such as reverse display). Then, a style content setting screen for the selected character string / style name is displayed. On the style content setting screen, for example, style items to be set are listed as shown in FIG. 8, and for each of these items, a value is entered using a keyboard, or a previously prepared candidate value list is called. The style contents are set by, for example, selecting a desired one from among them. Items not set by the user
Interpreted as a given default value. When the style content is set, the typeface and character size of the character string in the document content display section 610 are changed according to the set content, and the result of the style setting can be visually confirmed.
By performing such a style setting for all the style names in the style name list 620, the style setting is completed. The set style contents are stored in the storage unit 220.
Is registered in the style template 222 in.

Although not shown in the example of FIG. 7, it is also possible to generate a layout frame on a page and paste a character string there. In this case, the identification information of the layout frame to be pasted is set in the style content of the style name of the character string in the style template. Note that the manner of associating the layout frame with the character string is not limited to the method of setting the exemplified identification information of the layout frame in the style content.

When the style template is completed in this way, automatic typesetting processing becomes possible.

[Automatic Formatting] When automatically formatting an SGML document, a user first inputs an SGML document to be formatted to the structured document front end unit 10, specifies a conversion table to be used, and converts the format into a formatted document. Instruct conversion. Thus, the document conversion unit 108 converts the input SGML document into a formalized format document in the same procedure as that described when converting the template SGML document.

When the typesetting document is input to the typesetting editing unit 20 and a style template to be used is designated and automatic typesetting processing is instructed, the typesetting processing unit 230 executes the style content of each style name registered in the style template. According to the above, each character string of the typesetting document is typeset.

[Generation of SGML] If a character error or the like is found as a result of the automatic typesetting as described above, in the present embodiment, the error can be corrected by the UI of the editing processing unit 210 of the typesetting editing unit 20. . And in this embodiment,
The document changed on the typesetting editing unit 20 in this manner is converted to SGML.
By providing a function to perform the inverse conversion, processing efficiency is improved. In other words, the correction on the typesetting editor 20
The change is made to the typesetting document 224. The changed / modified typesetting document is passed to the structured document front-end unit 10, and the above-described S
By performing the conversion in the reverse direction of the conversion from the GML to the typesetting format, an SGML document can be obtained.

In this inverse conversion, SGM such as <Note on using P auto> and <T auto> (see FIG. 2)
The range governed by the style tag indicating the content automatically generated at the time of conversion from L to the typesetting format is deleted because it is not in the original SGML document. The attribute information inserted as the comment format is incorporated into the element tag of the corresponding document element, and is in the SGML format. Also, the style tags built in for the table are cleared,
It is returned to the original SGML form.

In this reverse conversion, it is necessary to generate a tag of a document element having no character string in the element content. For this, all the element names of the higher order of each document element are indicated in the conversion table. Therefore, a tag of a document element having no character string can be generated based on this.
In addition, the character string of the moved document element can be returned to the original position in the original SGML document by referring to the description of the return destination. In this way, by using the conversion table, the typesetting document can be correctly returned to the SGML document.

If this reverse conversion function is used, an SGML document can be generated from a document created by the typesetting editing unit 20 from the beginning. In this case, first, text is input from the keyboard to the document content display unit 610 on the editing screen (FIG. 7) of the typesetting editing unit 20, and a style name list 620 of a desired style template is called. Then, a character string in the document content display section 610 is designated as a range, and linked to the style name in the list 620. Thus, when the character strings corresponding to all the style names can be specified, one document is completed on the typesetting editing unit 20. This is converted by the structured document front-end unit 10 using the conversion table, so that an SGML document can be obtained.

[Effects] As described above, according to the present embodiment, first, a list of style names for which style contents need to be set is created by the style template creating unit 106, and the user sets the style contents accordingly. The style setting work can be facilitated without confusing which element should be set with the style content as in the related art.

Further, according to the present embodiment, the SGML is realized by using the conversion table and the style template.
Automatic typesetting of documents became possible. In this embodiment, since a conversion table and a style template can be easily created, even when handling various types of SGML documents having different DTDs, it is possible to perform automatic typesetting with less time and effort than before.

Further, according to the present embodiment, since the style name is managed so as to be unique, it becomes possible to uniquely specify the SGML document element from the style tag of the typesetting document. As a result, SG for formatted document
Conversion to ML documents is now possible. Also, SGM
Since a mechanism for incorporating the attribute information of the L document into the typesetting document is provided, the attribute information can be reflected on the SGML information in the reverse conversion.

In the present embodiment, a mechanism is provided for incorporating a character string that is not in the SGML document into the formatted result, and the character string thus incorporated can be distinguished from a character string that was in the original SGML document. A style tag (that is, a reserved word “auto” is added to the style name in the above example) is used. As a result, a character string that was not in the SGML document can be reflected only in the typesetting result, and can be deleted when the character string is converted back to the original SGML document.

Although the above description has been made with reference to the formatting of an SGML document as an example, the present invention is also applicable to structured documents other than SGML, for example, documents such as XML and HTML.
